How to Compress PDF Files and Reduce File Size

PDFs are perfect for sharing documents, but sometimes they get too big in size, especially those that contain images, scanned pages, or graphics. A large-sized PDF might be very slow during upload, hard to send via email attachment, and could occupy excessive space on your phone or laptop. To fix this, you can compress your PDF and decrease its file size with no change to the actual content.

What is PDF compression?

PDF compression includes the reduction in size of your document by optimizing images, removing unnecessary data, and cleaning up the document. The text and layout remain the same while the file gets lighter and becomes easy to share. For example, a 10 MB PDF can reduce to 2–3 MB after compression.

Why Compress a PDF?

There are many simple reasons:

• Easy sharing: Email services have file size limits; therefore, smaller PDFs send faster.
• Faster uploading: most websites and government portals accept small PDFs only.
• Save storage: Compressed PDFs utilize less memory on your device.
• Better performance: Smaller files open quickly on mobile phones.
• Ideal for scans: PDFs from scans are normally heavy, so it helps a lot with compression.
